I bought this in 2010, I had to repair them after a couple of hours of use but since the repair they have been great!

I'm updating my review. Mine too quit after a few hours of use but before I threw it away, I tore it apart and found a bad soldering job. One wire off another almost off. I resoldered and it now works again.

I've had 2 of these and both have now failed in less than 18 mos. I cracked one open and they are flimsy and poorly made but the only ones with dual ear volume control and independent mic and ear volumes... too bad not more robust and sturdy

We bought this in Sept of 2014, used very little before winter then today on our first spring ride the device is shorted in side the controller and the noise was so loud we had to unplug it from my wife's helmet.

Purchased controller and installed it in the summer of 2012. When you mount controller on the left side passenger grip, make sure you turn controller to the outside so that rain cannot enter controller. Contoller worked fine until got caught in a steady rain,volume control has quite working, push to talk control still works. Will be replacing with different type of controller
